/*
 * HelpCounter — Home Access Portal Stylesheet
 * Used by: /home  (volunteer home access portal)
 *
 * Design principles:
 *   - Mobile-first: base styles target small screens; breakpoints add desktop layout
 *   - Friendly and approachable — volunteers are community members, not staff
 *   - Card-based layout works naturally on both mobile and desktop
 *   - 16px minimum input font size to prevent iOS automatic zoom on focus
 *   - Touch-friendly tap targets (minimum 44px height on interactive elements)
 *
 * Breakpoints:
 *   sm: 36em  (576px)  — small phones in landscape, larger phones
 *   md: 48em  (768px)  — tablets
 *   lg: 64em  (1024px) — desktop
 *
 * Color contrast ratios:
 *   --color-text    #1f2937 on white  12.6:1  AAA
 *   --color-muted   #4b5563 on white   7.0:1  AAA
 *   --color-primary #1d6e3c on white   7.2:1  AAA  (green — volunteer theme)
 *   status pending  #92400e on #fffbeb 6.3:1  AA
 *   status approved #15803d on #f0fdf4 5.3:1  AA
 *   status denied   #b91c1c on #fef2f2 5.6:1  AA
